1. What is the Calories Burned Formula?

The calories burned formula estimates energy expenditure during physical activity using the Metabolic Equivalent of Task (MET) value, weight, and exercise duration. It provides a scientifically-based estimation of calories burned during exercise bike workouts.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( MET \) — Metabolic Equivalent of Task (unitless)
• \( Weight_{kg} \) — Body weight in kilograms
• \( Time_{hours} \) — Exercise duration in hours

Explanation: The MET value represents the energy cost of physical activities. One MET is defined as the energy expenditure while sitting at rest.

3. Importance of MET Value

Details: MET values are standardized measurements that allow comparison of energy expenditure across different activities. For stationary biking, MET values typically range from 4-12 depending on intensity.

4. Using the Calculator

Tips: Enter MET value (typically ~7 for moderate cycling), weight in kilograms, and exercise time in hours. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical MET value for exercise biking?
A: Moderate cycling typically has a MET value of 7-8, while vigorous cycling can reach 10-12 METs.

Q2: How accurate is this calculation?
A: This provides a reasonable estimate, but individual factors like fitness level, body composition, and exercise efficiency can affect actual calorie expenditure.

Q3: Should I use kg or pounds for weight?
A: The formula requires weight in kilograms. To convert from pounds, divide by 2.2.

Q4: Can I use minutes instead of hours?
A: Yes, but you must convert minutes to hours (divide by 60) before entering the value.

Q5: Does this account for afterburn effect?
A: No, this calculation only estimates calories burned during the exercise session itself, not the additional calories burned afterward.
